8-6 Cleaning the Gap Plate (suction type gas detector PE-2DC)
①
Detach the two hexagon socket head bolts from the gap plate using hexagon wrench.
Size of the hexagon socket head bolts is different (M5 and M6).
②
Slowly detach the gap plate and remove three O rings (P5, P6, and TPG-6).
③
Wipe off dust and dirt on the gap plate and gas detector’s main body with a soft cloth.
④
Assemble the gap plate by the opposite procedures from above.
Make sure the three O rings and spring washers are attached in their correct positions.
Turn OFF the power of the main body before cleaning the gap plate in order to prevent a fire or explosion.
WARNING
Be careful not to damage the joints of the gap plate or the side of the electric compartment. Damage to these
parts decreases the equipment’s explosion-proof properties.
CAUTION
If you need to detach the filter with a flow checker to carry out the above, loosen the joint to detach it.
